65 Zirconium Silicate Beads Zirconia Grinding Media 2.8-3.0 mm for Paint,Coating,Ink
1. Product Description of Zirconium Silicate Beads
Zirconium silicate beads contains 65% ZrO2,so it is also called as 65 zirconia beads. It plays an important
role in grinding application.
Compared with 95 Yttrium stabilized zirconium beads,65 zirconia beads has more competitive price/performance
ratio,which is suitable for grinding and dispersion of materials in low and medium viscosity.

3. Main Aplications of Zirconium Silicate Beads
Grinding and dispersion for Calcium carbonate, kaolin, zircon sand, titanium dioxide, pigment, dye, ink,
paint,coating etc.
4. What is the difference between zirconium silicate beads and ceramic beads blasting media?
Firstly, different Production process: Zirconium silicate beads is made by sintering process,while ceramic
beads is made by melting process;
Secondly,ceramic beads blasting media contains 7-13% Al2O3,it is different from zirconium silicate beads
from the chemical composition.
Thirdly, zirconium silicate beads has higher bulk density and true gravity than the one of ceramic beads
blasting media.
Forthly, different particle size distribution: zirconium silicate beads has wide specifications from 0.2-10mm,
while ceramic beads has narrow particle size distribution from 0-0.850mm.
Fifth,different usage: zirconium silicate beads is used as grinding media,while ceramic beads is used as
blasting media.
